Description
Technical field
The invention belongs to automobile technical field, relate to the gas barrier of a kind of frock, particularly a kind of automobile cavity.
Background technology
In the manufacturing process of automobile, after having welded, car body needs to carry out pre-treatment and electrophoretic process, and make car body there is good antirust and resistance of aging.Electrophoresis is, by charge movement, electrodeposited paint film is attached to car body surface, and electrodeposited paint film coating is even, smooth, smooth, has good hardness, adhesive ability, rotproofness and shock resistance.Pre-treatment is before electrophoretic process, to remove the corrosion of car body surface and impurity, plays the effect that improves electrophoretic process quality, and pre-treatment mainly contains the steps such as washing, pickling.
But when car body carries out pre-treatment and electrophoretic process, the part cavity in car body, owing to not having venting hole to cause air not to be discharged from, forms air chamber, and acidic liquid can not fully be contacted with the top of cavity with electrolytic solution.Therefore, the pre-treatment weak effect at cavity top, cavity surface also cannot form electrodeposited paint film in electrophoretic process, has reduced the corrosion resistance of car body.
In prior art, for existing vehicle, conventionally can adopt and make up in two ways above-mentioned manufacturing deficiency: 1, the forming mould of car body corresponding section part be carried out to die sinking again, at the top design venting hole of corresponding cavity, in pre-treatment and electrophoretic process process, by hydraulic pressure, in time air is discharged from venting hole; 2, increase postprocessing working procedures, to failing to form the cavity end face of electrodeposited paint film, clean and rust prevention by applying liquid material paint, play rust inhibition.
But through theoretical investigation and cost estimating, the problem that above-mentioned scheme exists is: 1, the tooling cost of mould is higher, and die sinking need to drop into 3,000,000～4,000,000 funds again, has improved the manufacturing cost of automobile; 2, the sticking power of rust-inhibiting paint and the resistance to corrosion electrodeposited paint film that is far from is good, and in actual use procedure, rust-inhibiting paint easily comes off, and work-ing life is low; 3, increase operation and improved workman's labor capacity, and reduced production efficiency, make the mean yield of automobile 25% left and right that declines.
Summary of the invention
